Effect of Different Decomposer Application in Shredded Trashes and Raw Trashes Composting and its Influence on Soil Nutrients and Productivity of Sugarcane in Alfisols of Tiruchirappalli District
Sugarcane cultivation is proud to the farming community as its useful in the production of high-value products. In addition, it produces voluminous trash which is nutrient-rich biomass. Burning of sugarcane trash has caused health-related issues as well as acted as an important factor in global warming. The aim of this study was to convert trashes into compost by degrading it through microbial inoculants. The study consists of three treatments, PUSA decomposer (4 capsules/tone of trash), TNAU Biomineralizer (2kg/tone of trash) and Cow dung slurry (5%) with shredded trashes and raw trashes. A more sugarcane cane yield of 87.2tha-1 was recorded in PUSA decomposer treated plot and it was 7.12 % over the control plot (81.4 kgha-1). More microbial population in the surface layer was 19.96 x106/g, 8.36 x103/g and 6.99x103/g of bacteria, fungi and actinomycetes respectively in the PUSA decomposer applied treatment in shredded trashes followed in TNAU Biomineralizer with raw trashes applied plot (19.63(x106/g), 8.30 (x103/g) and 6.74(x103/g) respectively) when compared to control. Further, use of implements like shredder helps in rapid decomposition and eventually increases the soil nutrient stages. The results shows that, in-situ sugarcane trash composting has increased the organic carbon, available nitrogen, available phosphorus and available potassium content in soil from 0.34 to 0.0.39%, 228.7 to 268.2 kgha-1, 7.80 to 9.91kgha-1 and 354.0 to 394.5 kgha-1 respectively. Therefore, in-situ composting with efficient decomposers like PUSA decomposers and TNAU Biomineralizer can be a good alternate to mitigate these problems.
SEED BIO-PRIMING WITH PGPR ON IMPROVING PLANT GROWTH CUCUMBER UNDER INVITRO AND INVIVO CONDITIONS
The study was conducted to evaluate the microbial seed priming technique in cucumber using Plant Growth Promoting Rhizobacteria (PGPR) and Biocontrol Agents (BCAs) for uniform seedling emergence, fast and early growth to escape the plants from biotic and abiotic stress both under green house and field condition. The treatment T9 (microbial primed with (Az.b + B.m +P.f + T.h)) had enhanced the plant growth by increasing the mean no. of leaves to 34.44 with the lengthiest internode of 21.20 cm/pl with more no. of internodes that 21.65, compared with the unprimed control (7.68, 4.95cm/pl and 6.50) respectively in green house condition. The same trend was followed in field also. The number of days taken for tendril initiation and 50 per cent flowering was 21.69 and 41.01 in green house and 30.57 and 43.92 under field condition. It was very early when compared with the unprimed control. It took 46.42 and 71.11 mean no. of days to initiate the tendril and to attain 50 per cent flowering in control under field condition. Microbial seed priming also influenced the yield parameters, viz., Average no. of fruits/pl (27.75) and enhanced the fruit weight of 298.09 g/fruit which is about 8.27 kg of yield / pl. in the best treatment T9. The average fruit weight (179.81 g/fruit) and yield (2.17 kg/pl.) is very low in unprimed control. From the above experiment, it was clearly shown that microbial seed priming has a definite impact/ influence of enhanced growth and yield in cucumber.
Augmenting the productivity of Barnyard millet through crop establishment and nutrient management techniques in sodic soil
Barnyard millet is one of the hardiest, climate resilient and fast growing crop that is bestowed with high nutrient content in grains. An experiment was carried out in barnyard millet under natural sodic soil condition to study the effect of different methods of crop establishment and to optimize the nutrient requirement for barnyard millet (Kudiraivali) under sodic soil condition using the short duration high yielding variety Co (KV)2 during kharif season in 2016 at Anbil Dharmalingam Agricultural College and Research Institute. The experiment was carried out in FRBD comprising two factors viz., crop establishment techniques like line sowing at 25 x 10 cm (E1) and 35 x 10 cm (E2) and transplanting at 25 x 10 cm (E3) and 35 x 10 cm (E4) and nutrient management practices of N1 at 75 %, N2 100% and N3 125 % recommended dose of fertilizers. The experiment was replicated thrice. Totally twelve treatment combinations were analyzed. Results revealed that transplanting of barnyard millet at 35 x 10 cm with 125 % RDF recorded higher grain yield of 980 kg/ha with increased growth parameters like plant height, number of tillers and yield attributes viz., number of panicles, length of panicle and weight of the panicle in sodic soil.
Disease Resistance could be augmented by Bacterial Metabolites
Pseudomonas fluorescens (Pf1) showed maximum Indole Acetic Acid (54.70 µg ml-1) (IAA), Salicylic Acid (SA) (28.10 µg ml-1) and siderophore production was 9.30 micromoles benzoic acid ml-1. Similarly Pf1 recorded higher amount of HCN with 0.08 (1 unit= 0.001) absorbance. From the above study it reveals that bacterial metabolites may also contribute to the disease resistance. Besides the capacity to colonize roots intensively for an extended period of time. the production of these siderophores has been linked with disease suppressing ability of certain species of fluorescent pseudomonas.
Chemical and Mechanical options for Management of Weeds in Sugarcane in Cauvery Delta Zone of Tamil Nadu
In Cauvery Delta Zone (CDZ) of Tamil Nadu, Sugarcane is an important commercial crop with wider spacing and lond duration which suffers from weeds where weed management studies are vey meagre. Therefore, the present experiment was conducted during the special season of 2016-17 to 2018-19 at Sugarcane Research Station, Sirugamani, Tamil Nadu to evolve suitable weed management practices for weed control in Sugarcane in the CDZ for increasing the cane yield. The experiment was laid out in RBD replicated thrice with 8 treatments using TNAU Sugarcane Si8 as test variety. The treatments consisted of pre emergence herbicides in combination with post emergence herbicides or weeding by power tiller or intercropping with daincha. The crop yield parameters, weed control efficiency and economics were observed. Significantly higher cane yield (123.3 t/ha), highest net income (Rs. 2,11,220/ha) and BCR (3.02) along with highest weed control efficiency (50.4%) at 240th day was recorded with application of Pre-emergence herbicide (atrazine @1.00 kg/ha) and post emergence herbicide (Metribuzin @ 0.75 kg/ha) at 60 days after planting.
